TERMINAL FOR ELECTRIC WIRES.

Specification of Letters Patent.

Patented Mar. 21., 1916.

Application filed October 11, 1915. Serial No. 55,211.

To all whom it may concern:

Be it known that I, Jnssnr. M. Wrnrn, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Terminals for Electric WVires, of which the following is a specification.

My invention relates to lmprovements 1n terminals for electric wires, and more; particularly to a terminal which is designed primarily for use on electric conductors of automobile engines, although, of course, my improved terminal is capable of a wide range of usefulness outside of this particular art.

A further object is to prov de an mproved construction of terminal which economizes space and which 1s securely gripped to the conductor or wire, so that there is no possibility of accidental disconnection.

A further object is to provide a terminal which can be manufactured and attached at reasonably small cost, and which Wlll most effectually perform the functions for which it is intended.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Flgure l is a view in elevation illustrating my 1mproved terminal in position on an electric conductor. Fig. 2 is a perspective view showing the manner of connecting the conductor and the terminal, the latter shown in its position before bending. Fig. 3 is a view in transverse section on the line 33 of Fig. 1, and Fig. 4 is an end elevation of Fig. 1.

My improved terminal comprises a metal plate 1 whichat its intermediate portion is curved as shown at 2, and at its ends is provided with openings 3 for the reception of a binding post or other electric connection (not shown). The extreme ends of the plate are cut away or rounded as shown at 4 to economize metal and space, and the openings 3 may be formed in the plate before bending or after bending as desired, the latter being preferable as it insures the proper registration of the openings, although I have shown in Fig. 2 the openings as in the plate before bending.

The curved intermediate portion 2 is slit adjacent one edge of the plate as shown at 5, and the metal at the end of the plate is bent downwardly as shown at 6, permitting an entrance of an electric wire 7 into the opening formed by the slit 5. This is the first position of the parts in assembling, and after being so positioned as indicated in Fig. 2, the wire 7 is bent against the under or concaved face of the curved portion 2, and the two ends 8 of the plate, which I shall hereinafter refer to as perforated ears are bent together.

As is customary, the electric wire or conductor 7 is inclosed in a casing 9 of insula tion, and this casing of insulation is inclosed in the curved portion 2, so that while the bent or hooked end of the wire 7 is secured, the insulated portion 9 is also inclosed and secured.

When the ears 8 are pressed tightly together, a notch 10 is forced out of the cylindrical portion 2, so that a portion of the metal is projected into the insulated covering 9 and operates to prevent any possibility of movement of the electric conductor. Furthermore, this notch or bite 10 permits a nut or washer to be accommodated in the minimum of space.

In Fig. 4, it will be seen how the notch or bite presses into the insulation 9 of the electric conductor, and a firm rigid fastening is had.

Various slight changes might be made in the general form and arrangements of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. An electric terminal, comprising a metal plate having its intermediate portion curved and adapted to be positioned around an electric conductor, the ends of said plate located side by side and having bolt-receiving perforations therein, and one of said ends having a curved recess or notch in the bent intermediate portion, whereby a bite is had into the conductor and a space is provided for a nut, substantially as de- 1 10 ductor having insulation thereon, of a terconductor and providing a nut-receiving minal comprising a plate having its interspace, substantially as described. mediate portion curved and positioned In testimony whereof I have signed my around the electric conductor, the naked name to this specification in the presence of 5 end of the conductor projecting through a tWo subscribing witnesses.

slot in the plate the ends of the plate 10- cated side by side and having registering JESSEE MERCER WHITE" openings therein, and said terminal at one Witnesses:
